Questions tagged [qtableview]

QTableView is a Qt class providing a default model/view implementation of a table view.

A QTableView implements a table view that displays items from a model. This class is used to provide standard tables that were previously provided by the QTable class, but using the more flexible approach provided by Qt's model/view architecture.

QTableView implements the interfaces defined by the QAbstractItemView class to allow it to display data provided by models derived from the QAbstractItemModel class.

The official Qt documentation can be found here for Qt 4.8 and here for Qt 5.
